The automatic core cutter uses a highly reliable servo motor control system to perform the function of the haul-off unit, with the cutting line speed steplessly adjustable within 1-150M per minute. Tube feed length measurement uses a high-precision rotary encoder with a measuring accuracy of up to 0.05mm. The control system uses a Siemens PLC programmable controller, combined with a powerful 320-240 touch screen that displays and sets various kinds of information. It makes it easy to set and execute a range of functions, including the running speed of the core cutter, cutting length and number of pieces cut.
